1.	a 0.1 kg ball moving at a speed of 5m/s in +x direction collides head on with 0.3kg ball that is at rest. Assuming that collision is elastic, determine the final velocities of the two balls
Answer» Since collision is elastic relative velocity of approach = relative velocity of SEPARATION n 1 =v 1 /3+u 2 u 2 =2V 1 /3 CONSERVING momentum m 1 v 1 =−m 1 3 v 1 +m 2 v 1 /3 0.1 3 4V 1 =m 2 2v 1 /3 m 2 =0.2 kgExplanation:
